New insights into secondary gas generation from the thermal cracking of oil: Methylated mono-aromatics. A kinetic approach using 1,2,4-trimethylbenzene. Part II: An empirical kinetic model

Eventually, the four-equation empirical model was used to perform simulations under temperature conditions usually encountered in deeply buried reservoirs (DBR). Under these conditions, the simulations revealed the CH4 prone character of methylated mono-aromatic hydrocarbons. Moreover, these simulations demonstrated that the thermal stability increased as follows: methylated polyaromatics < methylated mono-aromatics < saturates. The risk for the decrease in the porosity of reservoirs was also quantified via the prediction of the yield of (prechar + char) components.
